# [Tex/LaTex] Box for multiple lines and automatic width

boxes

I feel this is rather a dumb question, but I could not find an answer. I'm looking for a \parbox without the width parameter, i.e. it should be determinded by its content. And the content is multiple lines. Something like:

       A
I like B , but who cares?
C2


An \mbox or \makebox doesn't allow for line breaks, it seems and a \parbox wants a width parameter. There must be some easy solution for what I want, no?

How about a simple tabular?
